Mathematical modeling of starting modes and static characteristics of a wound-rotor induction motor in phase coordinates

The algorithms for calculating steady-state modes, static characteristics, and transients in an asynchronous drive based on a wound-rotor induction motor and a starter in a rotor circuit are presented. The calculation is based on a mathematical model of an induction motor that takes into account the saturation of the magnetic circuit. The electromagnetic processes are described by a nonlinear system of equations of electrical equilibrium composed in a fixed three-phase coordinate system, the coefficients of which are the differential inductances of the circuits. The steady-state modes and static characteristics are calculated by solving the boundary value problem using the continuation method in the parameter.
